It seems an attractive mode ie eats up the CPU, needs
Code/Decode and is not as good as QRSS 3
I will avoid it and continue with CW and QRSS
Attractive !! I am joking

Subject: Re: LF: CPU and QRSS
Laurence,
On my old LF grabber PC it is easily possible
to run 6 SL instances without problems. But, if Opera bahaves about like ROS
regarding CPU load (i did some ROS VLF tests for a few days in 2010, until i
found that it cannot decode signals that were more than O copy in
DFCW-3), it would be a problem for that PC or at least at its limit.
A pity about loosing the ID of that traces in the ARGO screen, seemed to
have been OOO copy...
How many Opera decodes in AK so far, on
137?

Ive been playing with Opera and mixing it up with QRSS up in
Alaska on my poor old Dell. It appears the CPU is overloaded and the
result is some very strange things happening - Im still not sure exactly as
I have to collect audio for Argo at just 172Hz using 136KHz USA for running
parallel Opera but the attached is what it produced on the pre dawn Eu short
period "tilt/lift/short term attenuation reduction" that has occured a
couple of times this week, and Ive not seen before - the Eu dusk lift of
around 5dB lasts for appx 45mins.
I can decode DK7FC but there
appears to be another signal - or perhaps its an artifact. I dont think it
was Steve VE7SL who was down at 171 with a Strong "SL" a little later
in the morning. Time I got that additional processing power. Everything is
shifted up in freq as you can see and probably interrupts and allocations
going on..certainly not a Geo RF effect (or is it ??)
